Keysight (Agilent) 4339B High-Resistance Meter, DC

The Keysight 4339B High-Resistance Meter is a precision DC resistance measurement instrument spanning 1 MΩ to 100 TΩ with 10 µΩ resolution. It delivers stable, low-noise readings across insulation resistance, surface resistance, and volume resistivity characterization. A guard terminal minimizes leakage current effects in high-impedance environments. The dual display presents resistance and test voltage/current simultaneously, while selectable measurement times from 100 ms to 100 s accommodate dynamic and static test requirements. IEEE 488.2 GPIB control enables integration into automated test systems and data acquisition workflows.
